whisper

candle-whisper: speech recognition

An implementation of OpenAI Whisper using candle. Whisper is a general purpose speech recognition model, it can be used to convert audio files (in the .wav format) to text. Supported features include language detection as well as multilingual speech recognition.

Running some example

If no audio file is passed as input, a sample file is automatically downloaded from the hub.

 cargo run --example whisper --release

> No audio file submitted: Downloading https://huggingface.co/datasets/Narsil/candle_demo/blob/main/samples_jfk.wav
> loaded wav data: Header { audio_format: 1, channel_count: 1, sampling_rate: 16000, bytes_per_second: 32000, bytes_per_sample: 2, bits_per_sample: 16 }
> pcm data loaded 176000
> loaded mel: [1, 80, 3000]

In order to use the multilingual mode, specify a multilingual model via the --model flag, see the details below.

• --input: the audio file to be converted to text, in wav format.
• --language: force the language to some specific value rather than being detected, e.g. en.
• --task: the task to be performed, can be transcribe (return the text data in the original language) or translate (translate the text to English).
